A protocol for determining log NEQ and a new metric, the Equivalent Image Quality or EIQ, are presented for the generalized experimental evaluation of noise related monochrome pictorial image quality. These metrics are then applied to the evaluation of a pictorial CCD camera and several pictorial films. Emphasis is placed on the development and verification of experimental techniques which do not require elaborate equipment or support facilities. Data analysis is conducted using only available software packages and personal computers. Conclusions are drawn concerning the performance of CCD based and silver halide imaging systems which allow for the objective comparison of the images they produce, and the fundamental differences in the characteristics and requirements of the two systems as applied to pictorial imaging are noted.
